Ruiseñores y otros músicos “naturales”: Quevedo entre Góngora y Marino

El tan visitado motivo barroco de la música «natural» (o sea provocada por el canto de las aves y por otros sonidos de la naturaleza) se remonta a una tradición tanto clásica como románica. En particular el topos del ruiseñor, ya presente, en su doble vertiente de mensajero de dolor y de regocijo, en Góngora y en Marino, es retomado por Quevedo hasta culminar en un cruce de préstamos e influencias recíprocas. En el propio Quevedo se aprecia la tendencia a no distinguir entre varios cantores «naturales» y a transformar el clásico locus amoenus en una visión más descriptiva y anecdótica del paisaje. Ya no sólo filtrados a través de modelos elegíacos y petrarquistas, los cantores «naturales» (y quizá también artificiales) de Quevedo nos revelan así la evolución que, en las primeras décadas del siglo XVII, sufrió el concepto mismo de naturaleza. The baroque motive of natural music (i. e. provocated by the warbling of the birds and the noise of other natural elements) goes back to a classical and a romance tradition. In particular the topic of the nightingale, present in Góngora and in Marino as a symbol of both pain and joy, is developped by Quevedo in various poems caracterized by many reciproc influences. Moreover Quevedo shows a trend toward the contamination of different natural singers and the transformation of the classical locus amoenus in a descriptive landscape. No more filtered by elegiac and petrarchan models, the various natural (and perhaps artificial) singers of Quevedo reflect the evolution of the same concept of nature in the Golden Age poetry

Effects of chronic social stress on oligodendrocyte proliferation-maturation and myelin status in prefrontal cortex and amygdala in adult mice

Stress-related neuropsychiatric disorders present with excessive processing of aversive stimuli. Whilst underlying pathophysiology remains poorly understood, within- and between-regional changes in oligodendrocyte (OL)-myelination status in anterior cingulate cortex and amygdala (ACC-AMY network) could be important. In adult mice, a 15-day chronic social stress (CSS) protocol leads to increased aversion responsiveness, accompanied by increased resting-state functional connectivity between, and reduced oligodendrocyte- and myelin-related transcript expression within, medial prefrontal cortex and amygdala (mPFC-AMY network), the analog of the human ACC-AMY network. In the current study, young-adult male C57BL/6 mice underwent CSS or control handling (CON). To assess OL proliferation-maturation, mice received 5-ethynyl-2'-deoxyuridine via drinking water across CSS/CON and brains were collected on day 16 or 31. In mPFC, CSS decreased the density of proliferative OL precursor cells (OPCs) at days 16 and 31. CSS increased mPFC myelin basic protein (MBP) integrated density at day 31, as well as increasing myelin thickness as determined using transmission electron microscopy, at day 16. In AMY, CSS increased the densities of total CC1+ OLs (day 31) and CC1+/ASPA+ OLs (days 16 and 31), whilst decreasing the density of proliferative OPCs at days 16 and 31. CSS was without effect on AMY MBP content and myelin thickness, at days 16 and 31. Therefore, CSS impacts on the OL lineage in mPFC and AMY and to an extent that, in mPFC at least, leads to increased myelination. This increased myelination could contribute to the excessive aversion learning and memory that occur in CSS mice and, indeed, human stress-related neuropsychiatric disorders

in situ experimental tests on masonry panels strengthened with textile reinforced mortar composites

Abstract Textile Reinforced Mortar (TRM) composites are a retrofitting techniques used for strengthening masonry structures. The system is composed of dry fibers grids embedded in two layers of inorganic matrix. The paper describes the results of an in-situ experimental campaign on ancient masonry panels reinforced with different TRM systems. The tests were performed in a building located in Finale Emilia (north of Italy) built at the beginning of the last century. Four diagonal compressive tests were performed on unreinforced and reinforced walls. The walls were strengthened with different configurations: two panels were reinforced with a TRM systems composed of a lime mortar and two different types of glass fiber grids and twist steel bars used as anchors; one panel was reinforced with a layer of TRM on one side and a Near Surface Mounted (NSM) system on the other one. The results of the tests are described and a complete mechanical characterization of the reinforcement systems and of the masonry was performed to analyze the experimental results and validate simple analytical models

Quevedo con / sin Petrarca: apuntes para un debate

En este artículo, se propone un breve recorrido a través del petrarquismo quevediano demostrando una estrecha vinculación del poeta español con textos petrarquistas, pero también la tendencia a encontrar su unidad fuera de ellos. En la medida en la que sonetos, canciones u otros textos petrarquistas aparecen desviados y mediados por reminiscencias nacionales, Quevedo destruye su retórica y fragmenta la coherencia de su argumentación. Frente a la técnica moderna de la contaminatio gongorina, Quevedo ensaya más bien la postmoderna del pastiche y de la fragmentación. In this article, the author proposes a brief review of Quevedo’s poetry through the influence of Petrarch, proving a close relation between the Spanish poet and the Petrarchan texts, but also a tendency to find his unity out of them is shown. Quevedo destroys Petrarchan rhetoric and its coherence of argumentation, when his poetry is influenced by national reminiscence. While Gongora uses the modern technique of contaminatio, Quevedo prefers the post-modern technique of pastiche and fragmentation

Ancient masonry arches and vaults strengthened with TRM, SRG and FRP composites: Numerical analyses

[EN] The two arches and the three vaults experimentally described in Carozzi et al. (2017) are here analyzed with a novel robust FE lower bound limit analysis code, suitable to predict active failure mechanisms, lines of thrust and collapse loads in absence and presence of TRM, SRG and FRP reinforcement. The approach relies into a discretization into rigid-infinitely resistant quadrilateral elements for masonry, interfaces between contiguous elements exhibiting limited strength and perfectly bonded rigid-plastic trusses representing the reinforcement. For masonry, a No Tension Material NTM model can be adopted to compare with classic Heyman¿s results, but also a limited compressive and tensile strength with a cohesive frictional behavior in shear may be accounted for in a relatively simple fashion, i.e. in principle with the possibility to model shear sliding and compression crushing. Debonding and delamination of the reinforcement are considered in a conventional way, assuming trusses with a limited tensile strength derived from either experimental data available or consolidated formulas from the literature. With the knowledge of the exact position of the hinges provided by limit analysis, 2D FE static analyses with non-linearity and softening concentrated exclusively on hinges are carried out, to simply extend the knowledge beyond collapse loads estimation towards a prediction of initial stiffness and ultimate displacements. In all cases, promising agreement with experiments is observed.Part of the analyses were developed within the activities of Rete dei Laboratori Universitari di Ingegneria Sismica - ReLUIS for the research program funded by the Dipartimento di Protezione Civile.Bertolesi, E.; Milani, G.; Carozzi, FG.; Poggi, C.

new italian guidelines for design of externally bonded fabric reinforced cementitious matrix frcm systems for repair and strengthening of masonry and concrete structures

Abstract The paper summarizes the main features of a standardization activity carried out in Italy by the Ministry of Public Works, to which two of the authors have taken part, for the homologation and the acceptance of Fabric-Reinforced Cementitious Matrix (FRCM) composites. During the last years, such composite materials have becoming increseangly popular in the civil engineering field for strengthening existing constructions, even if difficulties can occur in their mechanical characterization that is strongly affected by different and complex failure mechanisms. The American ACI 549.4R-13 is currently the only available guideline for design and construction of these systems. In this framework, the paper describes the Italian proposals for the homologation process of FRCM materials as well as for the design of strengthening interventions with these composites. Comparisons with the American guideline are also reported together with some considerations regarding the different partial safety factors
